Hidden Backup Prince
Rumplestiltskin: Did I not tell you that I can have your son slay the dragon? And am I not a man of my word?So you have a setting with a monarchy, or where heredity is somehow important (say Superpowerful Genetics are in effect), and the entire royal / Super Family Team are under constant threat of being killed in a surprise attack by their enemies. Sure they'll fail 99% of the time, and most royal families have a Spare to the Throne to ensure there's a someone to inherit, but what to do in case they somehow wipe out everyone in the line of succession (who isn't evil)? Evil Only Has to Win Once after all. The solution is to raise one of the King's children as a commoner far away, without knowledge of their Secret Legacy. The idea being that they'll be safe in anonymity, and they may even be able to be trained or schooled in a way that spares them from becoming snobby and brings them closer to commoners. The Hidden Backup Prince isn't always created intentionally. The kid may be a bastard child and hidden to cover up their father's indiscretions, a twin who is sent away to avoid complicated succession rivalries, or is somehow kidnapped or separated unintentionally.note Of course, if the Hidden Backup Prince is resentful and finds out about their heritage they may decide to be the cause that wipes out the royal family. Nothing like going from Riches to Rags to motivate spite. Usually though, the Hidden Backup Prince will know nothing of their heritage yet somehow get involved in the plot regardless. See also Rags to Royalty. May overlap with Backup Twin. For the sake of keeping things simple, this trope will cover both intentionally and unintentionally creating a Hidden Backup Prince. Cases such as involuntary separation (through chance or enemy schemes) count. This trope can also be in play even if the royal family isn't killed off— the Hidden Backup Prince exists as a fail safe, regardless of if it's called into use by the plot.

King George: His what?!
Rumplestiltskin: His twin brother. Did I not mention there was another?

Anime and Manga
- In Go Lion, the royal family of Altia is killed, save for Princess Fala, who was taken away when the planet was attacked.
- The short-lived manga Barrage: It's revealed towards the end that Astro was the real prince all along; he was stolen shortly after birth and replaced with a "dark matter duplicate" so that he could be raised away from the corruption of the court.
- Magic Knight Rayearth: Princess Emeraude's younger brother Ferio. In the manga, he's Prince Incognito. In the anime, his memory of being royalty has been temporarily erased.
- Ooku: After a plague kills all male claimants to the shogunate, the previous shogun's nurse seeks out the only remaining member of the line, an illegitimate daughter who had been kept a closely-guarded secret, and puts her on the throne—at first in disguise, later openly ruling in, well, she stuck with her father's name but using her own face and female attire counted for much.
- Inverted in Fushigi Yuugi. The crown prince was a boy named Tendou, and in order to protect his life from one of the concubines, who wanted her son, Hotohori, on the throne, his father sent him to live as a commoner, with the intention of bringing him back to the royal family when the heat was off. Which never happened. Ironically, Tendou's ex-girlfriend Houki ends up being taken to be part of the Royal Harem, and ends up marrying Hotohori, who looks just like Tendou.
- Space Pirate Mito cites preventing her son from becoming the hidden backup prince as her primary reason for hiding him in the first place. (It didn't work.) She would have been perfectly happy to allow the usurper to continue ruling the galaxy if he'd just left her boy alone.
- In Shinmai Maou no Testament, Mio learns she's the daughter of the demon king after he's killed off, and a hostile demon faction is intent on finding and killing her. He had her hidden away to live the life of a normal human up to that point. Once Basara also learns of this, he reconsiders having kicked them out of his house after they tried to brainwash him into leaving.
- This is the case with Tenchi Masaki in Tenchi Muyo!. He is technically 2nd-in-line for the throne of Jurai (and probably, next-in-line since his grandfather probably doesn't want the crown anymore) but until recently, was ignorant of his heritage. Even now, his existence isn't known to the galactic community due to his grandparents' secret marriage.
- In the second season of Aldnoah.Zero, Asseylum's illegitimate half-sister Princess Lemrina is this for the Martian Empire. She is largely unknown to Vers society and confined to the Moon base just in case the Vers military needs someone who can activate Aldnoah in a pinch. It's a position she greatly resents.
Film - Animated
- In Justice League: Throne of Atlantis, the Queen of Atlantis left her son Arthur to be raised by his human father. Her plan was that by living in the human world, he would be able to understand them. Then, when he is retrieved and informed of his heritage, he would be able to bridge the gap between the two worlds and establish peace.
Film — Live Action
- In King Ralph after the entire British Royal Family is wiped out in a photography accident Ralph is found working as a lounge singer in Las Vegas and recruited to be the new King of England. He didn't know he was related to the monarchy at all - he's a royal bastard, his grandfather having been a Duke and his grandmother a hotel maid. The same is true of Sir Cedric.
- Princess Leia in Star Wars. It's a bit of a twist from the normal set up, but she and her brother Luke are being hidden from forces meaning them ill (though it's unusual for this trope that it be their own father). Which at least in her instance is especially ironic since she was a commoner and hidden by posing as royalty.
- Disney's The Man in the Iron Mask has the King's identical twin hidden in a cottage by their father to avoid a power struggle. The king being a jerk means as soon as he finds out he has a brother who might potentially try to usurp him he goes all out and has him jailed and put in the titular iron mask.
- This is the Backstory for the first two of Uwe Boll's In the Name of the King Thematic Series.
- In The Name Of The King has Farmer, who was presumed killed in a raid along with his mother. He was instead saved by a stableboy and raised as his own. It's possible the stableboy didn't even know who the kid was.
- In the Name of the King 2: Two Worlds stars Dolph Lundgren as Granger, a modern-day retired special forces soldier who gets sucked into the fantasy world of Ehb because he is the true heir.
- The baby prince hidden by the Black Fox and his band in The Court Jester.
- In the 1997 Prince Valiant film, Valiant was the heir to the throne of Thule, but when the kingdom was conquered by Vikings, the baby prince was saved and brought to Camelot. He was raised as a commoner and worked his way up to squire with no knowledge of his heritage, but his people had faith that he would eventually return and free them. He does and reclaims his birthright.
- Averted in A Brother's Price: Jerin's grandfather was Prince Alannon, who was kidnapped by enemy spies (Jerin's grandmothers) before his branch of the family lost the civil war and was executed down to the littlest toddler. However, Alannon couldn't have inherited the throne, due to an inversion of Heir Club for Men, but might have been executed, too, so he saw little use in revealing his identity. Jerin, on the other hand, does profit from his ancestry: It makes him a Suddenly Suitable Suitor to the princesses, who are descended from the branch of the family that won the war.
- Alexandre Dumas' Le Vicomte de Bragelonne, the second sequel to The Three Musketeers, better known through its film adaptations as The Man With the Iron Mask. It is about Louis XIV's supposed twin brother.
- In Wyrd Sisters, the king's infant son, Tomjon, is hidden away to protect him from his murderous relatives. Unbeknownst to everyone, there's a second son already there - Verence the fool. Though Nanny realizes at the end of the book that neither is the king's son; they're both children of Verence's father, the previous fool.
- Captain Carrot is implied to be the accidental version of this trope, but he has no interest in ruling Ankh Morpork, so its current ruler leaves him be.
- In Dragon Blood, the hidden backup prince is not, as such, hidden; everyone knows where he is imprisoned. His brother built an asylum and imprisoned him there, specifically to get rid of the competition. However, most people have forgotten over the time that Prince Kellen is quite sane, and could be used as replacement for high king Jakoven, who is a jerk and incompetent ruler. The rebels haven't forgotten, though, their plans involve getting Kellen out of the asylum and on the throne as soon as Jakoven has managed to piss off enough people so that most people would accept his younger brother as new king.
- Mia Thermopolis from The Princess Diaries was the illegitimate daughter of the Prince of Genovia. Since the Prince was unable to have anymore children due to his cancer treatment, he was forced to reveal to Mia that she is his only heir to the Genovian throne.
- The first Prince Geran from the Belgariad prequels was hidden away only after the rest of his family got butchered.
- In Split Heirs by Lawrence Watt-Evans and Esther Friesner, the King's people believe that twins are a sign of infidelity, so when Queen Artemisia gives birth to triplets, she gives two of them to a nurse who gives them to two other families to raise as commoners. The rest of the book is a hilarious deconstruction of Prince and Pauper tropes.
- In Andre Norton's The Prince Command, Michael was raised in America in total ignorance of his birth. Only when his grandfather and cousin died does he learn he was the rightful heir. (To be sure, this was the consequence of his father running away and marrying in America.)
- This trope is the backstory of "Daniel Draper" in Katherine Kurtz's Deryni works: he was born Prince Aidan Augarin Ifor Haldane and survived the massacre of his parents and six siblings when Prince Festil Furstan conquered Gwynedd in the year 822. The toddler is found hiding during the killings and smuggled out of the palace in a load of laundry by a loyal servant. In the book Camber of Culdi, an elderly Aidan is on his deathbed in 903 and reveals his identity to his Healer Rhys Lord Thuryn. He also "tells" Rhys of his son (who died in the Great Plague of 878) and his grandson, who has lived as a cloistered priest for the past twenty-four years.
- In Terry Pratchett's Nation, a flu epidemic has ravaged Britain to the extent that Daphne's father, a man previously 157th in line to the throne, is now heir apparent due to the fact he was sequestered away as governor of a remote Pacific island colony. The book deals with the search to finds him in the wake of a destructive tsunami...
- Prince Tobin in Lynn Flewelling's Tamir Triad is actually a hidden princess, hidden in plain sight via a hideous necromantic spell that involved sacrificing her twin brother at birth to protect her from her uncle the King's desire to subvert their nation's previously matrilineal monarchy through the simple expedient of massacring all of his female relatives. As a prince Tobin is safe, as a princess she's dead meat...and poor Tobin, who's been kept in dark for his own safety, doesn't know what to do when the spell starts to break down under the onslaught of puberty.
- A series of Succession Crises in the realm of Westeros in A Song of Ice and Fire have left more Hidden Backup Princes and Princesses than anyone knows what to do with. Matters stem from the collapse of the Targaryen dynasty, which had ruled Westeros for nearly 300 years before it was overthrown and supplanted by a new royal house, the Baratheons. King Robert I Baratheon sired nearly 30 bastard children, but no trueborn heirs. His officially recognized children and heirs were not actually his, but the products of incest between his wife and her twin brother. After their parentage is made public knowledge, their claim to the throne is disputed, but the royal army is the strongest force in the Seven Kingdoms, so they maintain their grip on power the old fashioned way. But waiting in the wings are even more potential successors with blood ties to the Targaryen royal family, including the two surviving children of the last Targaryen king, and their nephew: the eldest surviving son of their older brother (the former Targaryen heir apparent),who had been thought to be dead (and who might be an imposter). It turns out that after the Targaryen royal family was overthrown and the last scions were cast into exile, some Targaryen loyalists spirited away the late prince's son as a back-up, in case something should happen to the publicly known Targaryens. Things get complicated when the back-up prince makes himself known and launches an invasion before the last public Targaryen makes her move.
- Unconfirmed, but a very popular fan theory holds that Jon Snow is actually Rhaegar and Lyanna's son. If true, he could make a claim to the throne as well.
- And that's just the Iron Throne:
- After the death of King in the North Robb Stark with no known children, both Bran and Rickon Stark (thought dead) and Jon Stark (formerly Jon Snow, legitimized by royal decree are Hidden Backup Princes.
- Meanwhile, Theon Grejoy is a Hidden Backup Prince after his father King of the Iron Isles Balon Greyjoy dies and, Theon being presumed dead, his uncle Euron takes over.
- Lord of the Dreadfort Roose Bolton's bastard son Ramsay Snow invokes this by murdering his true-born half-brother. Roose isn't fooled for an instant, but arranges to have Ramsay legitimized anyway rather than father an heir on his second wife and risk his house being subject to misrule by a child lord or a Regent for Life.
- Inverted in Star Of The Guardians by Margaret Weis. Dion Starfire is hidden away because he's the only remaining heir to the throne, the remainder of the Blood having been killed during a coup staged by the current government, a People's Republic of Tyranny. The series begins because The Call Knows Where You Live.
- Lampshaded, like most everything else about fantasy literature, in the very tongue-in-cheek The Tough Guide to Fantasyland by Diana Wynne Jones. It notes that runaway princesses have an overwhelming tendency to marry "commoners of sterling worth" who more often than not turn out to be these.
- The entire plot of The False Princess by Eilis O'Neal, where the main character finds out at the beginning she was a decoy so that the real princess could be hidden away and protected.
- This is crossed with Changeling Tale in Trylle Trilogy. Wendy is a troll princess swapped with a human child in order to make sure that the evil Vittra trolls don't kill her.
- Crown Prince Alaric of Caederan in The Quest of the Unaligned is an example of this, though with the slight twist that it was done by accident: He was supposed to only stay in Tonzimmiel for about ten years before being informed of his heritage and taken to study with the finest mages in each of the four disciplines. This plane was unwittingly wrecked when Alaric's Tonzimmelian foster parents died and Alaric was spirited off by Tonzimmiel's orphanage system.
- Elemental Blessings: Rafe Adova is actually this to two thrones. His mother, Princess Subriella of Malinqua married into the royal family of Berringey as part of a peace treaty. The problem was that Berringey has the custom of killing off all extra royals once the crown prince was chosen, and Subriella drew the short end of the stick. Rather understandably, she took her baby and fled. She chose Welce, the small-and-out-of-the-way country that's the setting of the novels, since her empress mother knew about the regicide beforehand, and lived out the rest of her life in obscurity, birthing another son along the way.
- This is the basis for the plot of Spindle’s End by Robin Mc Kinley.
- Joe Abercrombie's The First Law plays with this, though it is eventually subverted when it is revealed that the hidden heir was no bastard son of the previous king but rather the son of a whore propped up by the series' resident chessmaster as a more pliant rule to succeed the current incompetent, dementia-suffering ruler and his spoiled heir.
- In Jennifer A. Nielsen's Ascendance Trilogy, the main character Sage turns out to be the kingdom's prince that had gone missing. Played with, both in that Sage was fully aware of his heritage and that he himself was the one who hid himself in an orphanage after he is presumably killed.
- In Vampire Academy, Jill Mastrano is an illegitimate heiress to the dying royal Dragomir family, who gets acknowledged in the finale of the series. Saving the family from near-extinction and losing its political rights. She herself had no idea of her status as she was raised in secrecy. A backup plan from Eric Dragomir.
- Enforced in The Magids by Diana Wynne Jones: the Koryfonic Empire, which spans multiple magical worlds, has all of the emperor's children raised by someone else to avoid rebellion and succession problems. The novel actually opens with the Emperor executing one of his sons for finding out the truth. Shortly after, the Emperor himself is assassinated, and the Empire is thrown into chaos as the protagonist, Rupert, tries to track down at least one of the heirs. (Some of whom are in our world and at least one of whom isn't fully human.)
Live Action TV
- In Power Rangers Samurai, Jayden and Lauren are heirs to the Shiba family that has led the battles against the monsters since for hundreds of years. During the battle that ultimately killed their father, they were split up; Lauren the firstborn went into hiding to train to defeat the Big Bad, while Jayden publicly fought off the monster attacks as the Red Ranger in the meantime. Played with in that one is Hidden and the other is explicitly the Backup. (Samurai Sentai Shinkenger, which this is based on, has a similar arrangement but doesn't quite count since Jayden's counterpart is merely a Body Double and not blood-related to the other.)
- Played absolutely straight in Once Upon a Time, with Prince James and his hidden backup twin, raised as a shepherd.
- In the King Arthur mythos Arthur doesn't know he's the heir to the throne, everyone thinks he's a foundling that Sir Ector took pity on; but Merlin trains him in such a way that he ends up a wise and humble king - unlike he presumably would have been if he had grown up as a prince. Arthur doesn't learn of his true parentage until after Uther, his father, dies and he pulls the sword from the stone... and commits Brother-Sister Incest with his older sister, Morgause.
- A later Medieval legend tried to paint Wamba, King of the Visigoths as this, in order to explain his (rather amusing) Crowning by Force. This is nonsensical because the Visigoths had an Elective Monarchy where bloodline didn't determine the next monarch.
- In the Shadowrun game's setting, the British monarch and several of the bloodline's heirs were reported dead in the wake of the second VITAS epidemic, throwing the line of succession over to a distant branch of the family. Claims that the previous royals hadn't died, but had goblinized into orks or trolls and been discreetly set aside in favor of their still-photogenic cousins, are a popular conspiracy theory in that Verse.
- In addition, the Japanese Imperial family were killed in a massive earthquake (shades of Harsher in Hindsight these days...), save for one young boy. Cue a new dynasty.
- Eberron: Karrnath, during the Last War, had a habit of pulling secret royalty out of nowhere right when they were needed, most notably Kaius III, who nobody had even heard of before he took the throne when Regent Moranna went off the deep end. Except Kaius III is in fact Kaius I and a vampire, pretending to be an example of this trope to let him retake open control of his nation without any awkward questions.
- Martin in The Elder Scrolls IV: Oblivion is the illegitimate son of the Emperor, who gave him away to a priesthood. When the Emperor and his legitimate sons are murdered by a cult he's the only one of them left (which is important, since someone of the Septim line is needed to foil the villains' Evil Plan). Given that his line have a habit of seeing the future, it's possible that he invoked this trope.
- Princess Elincia of Fire Emblem Tellius was brought up in secret this way, ready to assume the throne should everyone else die, because her parents were afraid of a succession conflict caused by her uncle already having been declared the successor when she was born.
- Alistair from Dragon Age: Origins is an accidental example; being a bastard, he would normally never have been considered for the throne, but he's the only one with Royal Blood left. He also was fully aware of his lineage since he was growing up. He also takes a lot of convincing, as he has zero experience, and is generally self-deprecating and wary of leadership. You can convince him to give it a go, let Anora take the throne, or convince them both to marry, or take the plunge with him if playing Human Noble Female player character.
- In Tales of the Abyss, Emperor Peony's backstory combines this trope with Self-Fulfilling Prophecy: the Score (an ancient prophecy that predicts the future without error) says that he'll be the one to take the throne despite having three older siblings and being an illegitimate son, so they send him to live in hiding in Keterburg with the excuse of keeping at least one potential heir away from the political scheming and backstabbing of the court. After said political scheming and backstabbing manage to do away with all his siblings, Peony then becomes the Crown Prince for lack of any other viable heirs. It's never made especially clear who, in all of this, knew that he was the one meant to come to the throne, and who was just being manipulated by the well-meaning Church, but it's certain that Peony himself never expected to actually inherit.
- In Vandal Hearts II, the death of King Zekras of Natra results in a war of succession between his sons Julius and Lagore; when the game begins, both brothers are dead, and by the end of the game, Lagore's son Franz is also dead while Julius' son Nicola has gone into exile. However, depending on decisions made by the player, the throne can ultimately be inherited by Zekras' illegitimate daughter Adele, who was raised believing she was the daughter of a local governor who married her pregnant mother.
- In Dragon Quest VIII, King Clavius's brother abandoned the kingdom years before the game took place. When it comes to light that the Hero is Clavius's nephew, he's all too happy to name the Hero his heir instead of his own worthless layabout of a son, Prince Charmles - helps that the Hero somewhat inadvertently passed the Rite of Passage (when attempting to help Charmles do the same).
- The main character of Divinity: Dragon Commander is the illegitimate offspring of the former emperor and his lover, a dragon in the guise of a human woman. Given that he has three legitimate elder siblings, is a bastard child, and half dragon, he'd ordinarily never be considered for the job. That all changed when his three siblings went insane and started a war that threatens the world. The wizard Maxos sough him out to solve this mess and rule in their place.
- In Guild Wars Salma was the illegitimate child of the Krytan King and a priestess, eventually following in her mother's footsteps. After the collapse of the royal family during the Charr invasion and the decline of the White Mantle, she was convinced to become queen and successfully led a civil war against the Mantle.
- Animaniacs: Yakko is appointed King of Anvilania this way, as he explains in song.
Yakko: I'm the cousin to the sister / Of son's niece's brother / Of the uncle's daughter's father / Of the nephew's sister's mother / And my grandpa's only cousin / Was the King's daughter's sibling, / But they're all gone,Crowd: So that is whyYakko: I am now your king!
- The Pirates of Dark Water: Prince Ren was raised by a lighthouse keeper unaware of his true heritage until the first episode. Hiding him was proven a wise move, considering Bloth had killed Ren's father's other heirs.
- Henry VII of the House of Tudor had a rather tenuous relationship to Henry VI of the House of Lancaster. His mother Margaret Beaufort was descended from one of John of Gaunt's legitimised out-of-wedlock sons (who were barred from the succession) and his father Edmund Tudor was of uncertain legitimacy as the timing of his parents' marriage could not be verified. He would therefore never have been considered for the throne if the more direct royal lines within the House of Lancaster had not been exterminated in the Wars of the Roses. One of Henry's first acts as king was to marry Elizabeth of York, uniting the House of Plantagenet's two rival cadet branches under a new dynasty of enhanced legitimacy, the House of Tudor.
- A number of imposters throughout history tried to invoke this trope by claiming to be an heir who had not been killed after all, e. g. Lambert Simnel and Perkin Warbeck during the reign of Henry VII. In Russia, the "false Dimitri" actually managed to overthrow the reign of Czar Boris Godunov. In France, over a hundred men claimed to be Louis XVII, the son of Louis XVI, somehow having escaped death in the Temple during the Revolution.
- Abd al-Rahman I survived three consecutive massacres of Umayyad family members and their supporters, and kept a low profile during an epic journey west from Damascus until he arrived in the Iberian Peninsula and founded the Umayyad Caliphate of Cordoba.
